Effect of Upadacitinib on Disease Activity, Pain, Fatigue, Function, Health-Related Quality of Life and Work Productivity for Biologic Refractory Ankylosing Spondylitis

Rheumatol Ther 2023; 10:679–91 doi 10.1007/s40744-023-00536-2

Upadacitinib significantly improved patient-reported outcomes in AxSpA patients with bDMARD-IR after 14 Weeks of treatment. There were notable improvements in disease activity, pain, fatigue, function, HRQoL, and work productivity.

Efficacy and Safety of Upadacitinib in Patients with Active Psoriatic Arthritis and Axial Involvement: Results From Two Phase 3 Studies

Arthritis Res Ther. 2023;25(1):56 doi 10.1186/s13075-023-03027-5

Evidence from two phase 3 RCTs showed that patients with PsA and axial involvement had greater responses when treated with a once-daily oral dose of 15 mg upadacitinib versus placebo, and a similar or greater response versus adalimumab. Safety results were comparable between patients with or without axial involvement.

Impact of initial therapy with upadacitinib or adalimumab on achievement of 48-week treatment goals in patients with rheumatoid arthritis: post hoc analysis of SELECT-COMPARE

Rheumatology (Oxford). 2022. Epub ahead of print doi: 10.1093/rheumatology/keac477

Post hoc analysis findings provide the first data evaluating the importance of treatment order with JAKinib vs TNFi as initial therapy, suggesting that a JAKinib first strategy leads to more rapid improvements in treatment outcomes following csDMARD failure.

Upadacitinib for the Treatment of Active Non-radiographic Axial Spondyloarthritis (SELECT-AXIS 2): A Randomised, Double-blind, Placebo-controlled, Phase 3 Trial

Lancet 2022 doi: 10.1016/S0140-6736(22)01212-0

Upadacitinib significantly improved the signs and symptoms of nr-axSpA compared with placebo at Week 14 in this investigation. Prior to this, upadacitinib had been shown to be effective in patients with AS. This study aimed to assess the efficacy and safety of upadacitinib in non-radiographic axial spondyloarthritis.

Long-term safety and efficacy of upadacitinib or adalimumab in patients with rheumatoid arthritis: results through 3 years from the SELECT-COMPARE study

RMD Open. 2022;8(1):e002012 doi: 10.1136/rmdopen-2021-002012

Upadacitinib continues to show consistently better clinical responses, compared with adalimumab, through 3 years, including rates of remission and low disease activity, physical function and pain severity.Following the favourable upadacitinib efficacy data seen in the SELECT-COMPARE study at 72 weeks, Fleischmann, et al. assessed the long-term safety and efficacy of upadacitinib versus adalimumab over 3 years in the long-term extension of this study, with promising results. ...

A review of JAK-STAT signalling in the pathogenesis of spondyloarthritis and the role of JAK inhibition

Rheumatology (Oxford). 2021. Epub ahead of print. doi: 10.1093/rheumatology/keab740.

JAK inhibitors are likely to become an important part of the overall treatment paradigm for spondyloarthritis (SpA).Although not fully understood, the pathogenesis of SpA is complex and thought to involve both environmental and genetic factors that together elicit a chronic inflammatory response involving the innate and adaptive immune systems. Several different cytokines, TNF, IL-17A, IL-12/23 and IL-23, which are directly/indirectly affected by JAK molecules, are involved in the pathogenesis o...

Upadacitinib versus Placebo or Adalimumab in Patients with Rheumatoid Arthritis and an Inadequate Response to Methotrexate: Results of a Phase 3, Double-Blind, Randomized Controlled Trial

Arthritis Rheumatol 2019 DOI: 10.1002/art.41032

UPA demonstrated superiority to ADA in terms of clinical, functional and patient-reported outcomes with comparable radiographic inhibition. As many RA patients fail to achieve LDA and remission with TNF inhibitors and MTX there is a requirement for additional treatment options. In this SELECT-COMPARE study the clinical and functional outcomes of UPA were compared to ADA in MTX-IR patients. 1629 MTX-IR were randomly assigned 2:2:1 to; UPA 15mg QD, ADA 40mg Q2W or PBO, with background MTX. Key end...

Pharmacokinetics of Upadacitinib with Clinical Regimens of the Extended-Release Formulation Utilized in Rheumatoid Arthritis Phase 3 Trials

Clin Pharmacol Drug Dev. 2019 Feb;8(2):208-216. doi: 10.1002/cpdd.462

Upadacitinib (UPA) extended release (ER) formulation dosing achieved the target profile that enables single dosing in patients with RA. In early clinical studies, UPA was given as an immediate release (IR) formulation, however patients were noted to experience fluctuations in blood plasma concentrations. To enhance patient compliance in UPA Phase 3 trials, ER tablets have been developed. Here, authors aimed at characterising the pharmacokinetics of UPA single and multiple doses of ER compared wi...
